“Cool stone chairs and an awesome view reward those who climb this short, steep Mesa Trail detour.”— Megan W
After enjoying the views, retrace your steps north and continue the Woods Quarry Trail by going uphill briefly and then contouring the hillside. After some gentle downhill, arrive at an optional 3rd Flatiron viewpoint, about 50 yards off the trail where the Woods Quarry Trail turns east to join the Mesa Trail.
Historical notes: The quarry provided sandstone for Boulder's buildings and sidewalks in the 1890's before more conveniently located quarries forced it to close in 1920. The Roosa Cabin was once a homesteader's residence and was occupied as late as 1970.
